CHECK-CONTROLLED DISPLAY MECHANISM.

Specification of Letters Patent.V

Patented Feb. 18, 1998.

Application filed November l5. 1906- Serial No. 343.627.

T0 all whom t 'may concern.'

Be it known that I, l/VALTER R. BENJAMIN, a citizen of the UnitedStates, residing at Granite City, in the county of Madison and State ofIllinois, have invented a new and useful Check-Controlled DisplayMechanism, of which the following is a specification.

This invention relates more particularly to means for displayingictures, such as stereo sco ic views and the ike, or other articles.

.`he primary "object is to provide a novel and simple machine, by meansof which articles to be displayed can be brought successively to view,and to employ in connection therewith, check or coin controlledmechanism of a simple and effective character that will, upon theintroduction of a check or coin, ermit the display of a predeterminednum er of pictures or articles, and the examination of each as long asdesired.

The preferred form of construction is illustrated 1n the accompanyingdrawings, where- 1n:-

Figure 1 is a perspective view of the machine. Fig. 2 is a verticalsectional view therethrough. Fig. 3 isv a sectional view at right anglesto Fig. 2. Fig. 4 is a detail sectional view on an enlarged scale,illustrating the check 'controlled mechanism in detail. Fig. 5 is a viewsimilar to Fig. 4, but illustrating the relation of the parts during theoperation of the machine. F ig. 6 is a detail sectional view on the line6-6 of Fig. 5. Fig. 7 is a detail sectional view on the line Similarreference numerals designate corresponding parts in all the figures ofthe drawings.

In the embodiment illustrated, a suitable upright casing 8 is employedhaving a top provided with an inclined portion 9, said top being alsoprovided with a window 10. The upper ends of the side walls are likewiseprovided with windows 11. These various windows are preferably of groundglass or other material that willpermit the passage of light, whilepreventing a view of the interior of the casing. A door 12 is located inthe upper portion of the rear wall, and is normally held closed by asuitableV lock 13. A stereoscope 14 is mounted on the inclined portion 9of the to rfn the present embodiment, a series of pictures 15 arecarried by spaced chains 16, and are loosely hung upon an annular shaft17 journaled in. the upper portion of the casing,

and having an exposed operating knob 18 at one end. The shaft is sodisposed that as the pictures pass thereover, they will be in properposition to be seen through the stereoscope 14, as will be evident fromFig. 2. It will of course be understood that other means than that shownfor mounting the views may be employed.

The shaft 17 is provided within the casing and contiguous to one of thes ide walls with a pinion 19, and a gear wheel 20, journaled as shown at21 upon the adjacent side wall, meshes with the pinion. f A dog 22,coperating with the teeth of the wheel 20, permits its rotation in onedirection, but prevents its retrograde movement. The wheel 20, asclearly shown in Figs. 4 and 5, is providedv on one side with aprojection 23, and this projection is normally engaged by a shoulder 24,

formed upon a detent lever 25 pivoted between its ends as shown at'26 toa late 27 that is secured to the side wall on w 'ch the wheel 20 isjournaled. The detent 25 is counterweighted, as shown at 29 in ordertonormally maintain the shoulder 24 behind the projection 23. A finger 29ais carried by the detent lever on the opposite side of its pivot orfulcrum to the shoulder 24, and is normally out of the path of movementof the projection 23, but if the detent is moved downwardly, so as todisengage the shoulder 24 from the projection 23 then the linger 29amoves into the path of movement of the projection 23, as illustrated inFig. 5.

A rearwardly and downwardly inclined check or coin chute 30 extends fromthe inclined portion 9 of the top to a point below the front or free endof the detent 25, the lower end of said chute being bifurcated as shownat.31 to receive the said end of the detent, whichprojects across thesame. The front side of the chute is open, but is provided with inwardlyextending flanges 32 to retain checks or coins of a proper diameter, butpermitting those of less diameter to drop from the chute.` A magnet 33is preferably located against the rear side of the chute between itsends. The front wall of the casing is slotted, as shown at 34, andis'closed by a vertically sliding plate 35, held elevated by an inwardlysliding staple 36 that normally receives the lock 37, said stapleprojecting p A pin 23.

and extends over the free portion of the detent 25. This guide isprovided with an inwardly extending spring 39, the lower portion ofwhich is disposed in the path of movement of the detent. Said detent isfurthermore provided between the shoulder 24 and the finger 29a with acam portion 4() that is located in the path of movement of theprojection 23 of the wheel, after the shoulder 24 has moved downwardly asufficient distance to release said shoulda/r.

A door 41 is located in the lower front wall of the casing, and is heldin closed position by a suitable lock 42. Through this door ac cess canbe gained to the lower part of the casing, for the purpose of securingthe checks or coins dropped in the machine, and a detachable rece tacle43 may be employed for receiving suc checks or coins. A funnel 44 ispreferably located in the lower portion of the casing below the viewsand above the receptacle, and in order that small children may readilyview the pictures, a shelf 45 is preferably mounted on the front wall ofthe casing, being supported by brackets 46 and a cleat 47 having notchesthat receive sets of supporting pins 48 carried by the front wall of thereceptacle.

The operation of the structure may be briefly described as follows.Under normal conditions, and as shown in Fig. 4, the shoulder of thedetent 24 is engaged with the Consequently, the wheel 2O is held againstrotation, and said wheel being geared to the operating and supportin(Tshaft 17, the pictures. cannot be moved. If however, a proper check orcoin is deposited in the coin `chute, the same will gravitate to thedetent and lower said detent sufficiently to disengage the shoulder 24from the projection 23. At the same time, said detent willbe carriedinto frictional engagement with the spring 39, which will prevent itsreturn movement, the wheel 20 being thus free, the shaft can berevolved. Upon its revolution, the pin 42 will rotate over the camportion 40, forcing the detent still farther down so as to insure therelease of the check or coin, which check or coin will fall to thebottom of the casing, passing through the funnel 44. The finger 29a,however, is now in the path of movement of the projection 23, and assaid projection revolves, it will engage the nger, returning the detentfrom its frictional engagement with the holding spring 39 to itsoriginal position. Consequently, when the projection 23 completes itsrevolution, it will again strike the shoulder 24. Thus, it will be seenthat a predetermined number of pictures or other articles will besuccessively brought to a position to be seen through the stereoscope orother view device, and each of these pictures can be examined as long asdesired. In case a check or coin of too small diameter is placed in thecoin chute, it

will gravitate through the open side thereof, and 1f a magnetic slug isplaced therein, it will be stopped by the magnet 33. When so stopped, orif the chute becomes choked from any cause, access can be readilyobtained thereto through the slot 34, by lowering the slide 35.

From the foregoing, it is thought that the construction, operation, andmany advan tages of the herein described invention, will be apparent tothose skilled in the art, without further description, and it will beunderstood that various changes in the size, shape, proportion, andminor details of construction, may be resorted to without departing fromthe spirit or sacrificing any of the advantages of the invention.
